54 V, 3.9 A AC adapter delivering 210 W for UniFi XG 6 PoE and USW-Ultra-210W switches with overload and temperature protection

  • TypeAC Adapters
  • Delivers 210 W output for demanding PoE switches
  • Wide AC 100-240 V input suits global mains voltages
  • Stable 54 V 3.9 A output matches UniFi XG 6 PoE requirements
  • Built-in voltage, current, temperature and overload protection safeguards connected hardware
  • Fireproof PC shell and pure copper core enhance durability

Compatible 210W power adapter

This 54V 3.9A AC adapter is built for UniFi XG 6 PoE and USW-Ultra-210W 6/8 port switches. It replaces the original Uacc-Adapter-AC-210W unit when a spare or replacement is needed. The adapter accepts AC100-240V input for worldwide mains compatibility.

210W output with protection circuits

The unit delivers a maximum output power of 210W at a steady 54V to drive PoE budgets across all connected ports. Integrated IC circuitry provides voltage, current, temperature and overload protection during sustained loads. A fireproof PC shell and pure copper core contribute to reliable long-term operation.

Direct replacement for UniFi switches

The connector and pinout match the UniFi XG 6 PoE (model US-XG-6POE) and USW-Ultra-210W switches exactly. No additional cables or converters are required for installation. Buyers who need a different voltage, higher wattage or a non-PoE power supply should look elsewhere.

Questions about this item

Will this 54V 3.9A adapter run my existing UniFi XG 6 PoE 6-port switch without changes?

Yes, the 210W output matches the switch requirement so the unit powers it directly.

How can I confirm the adapter is delivering 54V after I connect it?

The switch powers on and its status LEDs show normal operation when the adapter is working correctly.

Does the package include a mains lead or only the 210W brick?

The supplier title lists a power cord, so a mains lead is included with the adapter.
